The only one that matters by any notable amount is the 4th point. Halo will obviously push consoles en masse.
In the US I think the XBO can win, though it heavily depends on wether or not Sony will drop the PS4 price before the holidays. Star Wars, CoD, Assassin's Creed, MGS V and Destiny combined will give Halo a massive run for its money if their competing at price parity (Yes, I obviously know that I listed only multiplats, but Sony marketing for all of them will make a difference when you add it up).
So I think the XBO will win the US if the PS4 stays at 400$, but if the PS4 drops to 349$ I think the PS4 will win (unless they drop the XBO down to 299$).
Worldwide it's obviously no question.
